Bitcoin trades 24/7 on global exchanges, but its futures on the Chicago Mercantile Exchange (CME) follow limited trading hours. This mismatch leads to CME gaps – blank spaces on Bitcoin’s price chart when CME futures reopen at a different price than they closed. Below we explain why these gaps occur, highlight recent examples, analyze their impact on price, and explore how traders use CME gaps in their strategies.
Why Do Bitcoin CME Gaps Occur?
CME Bitcoin futures stop trading on weekends and even have a daily hour-long closure, unlike the continuous spot crypto markets. When Bitcoin’s price moves during these off-hours, the next CME trading session opens at a price that “gaps” above or below the prior close. A gap forms whenever there’s a difference between the futures market’s closing price and its next opening price due to CME’s downtime.
For example, if CME’s Bitcoin futures closed Friday at 50,000 USDT and by Sunday evening Bitcoin’s spot price jumped to 52,000 USDT, the CME futures would open around 52K USDT – leaving a 2K gap on the chart where no trading took place. These gaps happen because CME has fixed trading hours while crypto trades non-stop.
Recent Examples of BTC CME Gaps
CME gaps occur frequently, especially after volatile weekends. Here are a few recent instances and their outcomes:
- November 2024: Bitcoin futures opened about 77,930 USDT after a weekend, versus a prior close near 80,600 – leaving a gap in the 77.9K–80.6K range. This gap persisted for months until March 2025, when Bitcoin’s price dropped to around 76,700 and fully filled that gap.

- Early March 2025: A weekend rally saw CME Friday close around 84,500 USDT and Monday open near 95,300 USDT, creating a large gap between 84.5K and 95.3K. The very next day, Bitcoin retraced to about 83,500, closing this gap almost immediately. Such rapid fill shows how quickly the market can correct extreme weekend moves.
Tradingview
- Q1 2023: During a price surge, Bitcoin climbed above 28,000, which happened to fill a gap around 28K left from mid-2022 trading. Closing that gap was seen as an important price move at the time. However, the same rally created a new small gap near 27,000, showing how one gap’s fill can lead to another forming in fast-moving markets.
Trading view
- Unfilled Outlier: Not every gap fills promptly. As of March 2025, a gap between roughly 84,200 and 85,900 remained unfilled on the CME chart. This gap formed during a rapid price jump and had yet to see Bitcoin trade back in that range, making it an unusual case.

Impact of CME Gaps on Bitcoin’s Price Movements
Many traders closely watch CME gaps because Bitcoin has a tendency to revisit these price levels. Historically, CME gaps often act like magnets for price – gaps exert a pull that draws Bitcoin back to “fill” them sooner or later. Traders observe that gap zones can turn into support or resistance levels, as the price often pauses or reacts when revisiting the gap area.
For instance, an unfilled gap below the current price may make traders cautious, expecting a potential dip to “cover” that gap, whereas a gap above could entice bullish targets.
In practice, a majority of Bitcoin’s CME gaps eventually get filled. Analyses differ on the exact statistics, but sources suggest at least ~65% of gaps are filled over time. In fact, one study noted out of 80 identified Bitcoin CME gaps, all but one were ultimately filled. This doesn’t mean gaps fill immediately – some are resolved within days, while others have taken months or even years to close.
Generally, the market quickly fills routine small gaps during normal fluctuations. However, a gap that occurs during a strong breakout move might stay open longer if Bitcoin continues trending sharply away from that price. On the other hand, a gap near the end of a trend could signal a reversal, with the gap filling as the trend turns.
Overall, CME gaps add an extra factor in Bitcoin’s technical analysis, as traders weigh the likelihood of a gap fill when forecasting short-term price moves.
How to Use CME Gaps for Trading
Traders have developed strategies to take advantage of CME gaps, but these approaches require discipline and risk management. Here are a few common ways traders use CME gaps in trading:
- Gap-Fill Strategy: Since Bitcoin often retraces to fill gaps, some traders attempt to ride that move. For example, if a gap opened below the current price, a trader might wait for confirmation that price is dropping toward the gap and then enter a short position aiming to take profit when the gap is filled. Conversely, if a gap is above, a trader could go long targeting the gap’s level. The key is to confirm momentum toward the gap before entering, and exit once the gap closes to secure the intended gain.
- Support/Resistance Play: CME gap boundaries (the gap’s low and high) often act as support or resistance on the chart. Traders use these levels to make decisions. For instance, if Bitcoin is rising toward an unfilled gap’s lower bound, that gap level might act as resistance where the rally stalls. A trader could sell/short near that level, or conversely, if the price falls into a gap from above, the gap’s upper boundary might serve as support to buy. Using other technical indicators (moving averages, RSI, etc.) alongside gap levels can improve confidence in these trades.
Trading view
- Breakout Continuation Strategy: Not every gap fills right away – a gap that remains open may signal a strong directional move. If Bitcoin opens with a gap up and keeps rallying (showing no interest in filling it immediately), traders might treat it as a sign of bullish momentum (and likewise for gap down with bearish momentum). In this case, one strategy is to trade in the direction of the breakout, expecting the trend to continue.
Conclusion
Regardless of strategy, risk management is crucial when trading gaps. Gaps can create false signals and sudden volatility. Not every gap will fill, and timing is uncertain. Traders should set stop-loss orders in case the market moves against their gap prediction, and avoid over-leveraging on a presumed gap fill. Market conditions (news, liquidity) can change rapidly, so gap traders must remain flexible.
